•The use of derivative instruments may fail to protect or could adversely affect us;

Current report

Tariff actions by the U.S and other countries may adversely affect our business, financial condition and results of operations.

Current report

The current U.S. administration has implemented tariffs on imports from a broad set of countries, including Canada, Mexico, European Union member states, Japan and China. In response to these tariffs, global trading partners have or are likely to impose their own tariffs. Such U.S. tariffs and responsive tariffs have resulted in significant financial market volatility, and their impact on the global economy has been significant. Further effects of these tariffs cannot be predicted with certainty. Continued uncertainty surrounding trade policies and the potential for further tariff increases or the imposition of new tariffs may lead to a continuation or worsening of the impact of the tariffs on the financial markets, including the MBS, repurchase and equity markets. In addition, many economists and certain financial data have indicated an increased likelihood of U.S. and global recessions as a result of the disruptions to international trade. These trade actions and the widespread uncertainty and international tensions resulting therefrom may have a material adverse effect on our business, results of operations, ability to access capital, and financial condition and on the market price of our common stock.

Current report

The use of derivative instruments may fail to protect or could adversely affect us.

Current report

The availability of derivatives may not correspond directly with the interest rate risk for which protection is sought (e.g., the difference in interest rate movements for long-term U.S. Treasury Securities compared to Agency Securities) and the duration of the derivatives may not match the duration of the related liability.

Current report

Counterparties to a derivative agreement may default on their obligation to pay or not perform under the terms of the agreement and the collateral posted may not be sufficient to protect against any consequent loss. We may lose collateral we have pledged to secure our obligations under a derivative agreement if the associated counterparty becomes insolvent or files for bankruptcy. We may also experience a termination event under one or more of our derivative agreements related to our REIT status, equity levels and performance, which could result in a payout to the associated counterparty and a taxable loss to us.

Current report

Although we attempt to structure our derivatives to offset the changes in asset prices, the complexity of the actual and expected prepayment characteristics of the underlying mortgages as well as the volatility in mortgage interest rates relative to U.S. Treasury and interest rate swap contract rates makes achieving high levels of offset difficult. The credit-quality of the party owing money on the derivatives may be downgraded to such an extent that it impairs our ability to sell or assign our side of the hedging transaction. The value of derivatives may be adjusted from time to time in accordance with GAAP to reflect changes in fair value; downward adjustments, or “mark-to-market losses,” would reduce our net income or increase any net loss.

Current report

An inability to economically roll our TBA Agency Security transactions or to meet margin requirements on our TBA contracts could have a material adverse effect on our business, financial condition, and results of operations.

Current report

We utilize forward-settling transactions, including TBA Agency Security contracts, as part of our investment and hedging strategies. In a typical TBA transaction, we agree to purchase or sell Agency Securities at a future date, with the specific securities to be delivered determined just prior to settlement. To maintain our desired portfolio exposure, we often “roll” these contracts by entering into a new TBA contract with a later settlement date prior to the settlement of the original contract.

Current report

There is a risk that it may become uneconomical to roll our TBA Agency Security transactions. Market conditions, such as changes in interest rates, supply and demand imbalances, or increased volatility, may result in unfavorable pricing or wider bid-ask spreads for TBA contracts. If the cost to roll TBA positions increases significantly, or if the market for rolling TBAs becomes illiquid, we may be forced to either take physical delivery of the underlying securities or liquidate our positions at a loss. Either scenario could negatively impact our liquidity, leverage, and overall financial performance.

Current report

Additionally, TBA contracts are subject to daily margin requirements. If the market value of our TBA positions declines, we may be required to post additional cash or eligible collateral to our counterparties. In periods of heightened volatility or declining asset values, margin calls may be substantial and occur on short notice. If we are unable to meet margin calls in a timely manner, our counterparties may liquidate our positions, which could result in realized losses, reduced access to future financing, and reputational harm.

Current report

Any inability to economically roll our TBA Agency Security transactions or to meet margin requirements on our TBA contracts could have a material adverse effect on our business, financial condition, and results of operations.

Current report

Effective March 20, 2023, the Company committed to provide on demand a subordinated loan agreement to BUCKLER in an amount up to $200,000; this commitment has been automatically extended through March 20, 2027. Effective February 28, 2025, the Company committed to provide an additional on demand subordinated loan agreement to BUCKLER in the amount of $50,000 that extends through February 28, 2028. These commitments are collateralized by mortgage backed and/or U.S. Treasury Securities owned by the Company and pledged to BUCKLER. They are treated by BUCKLER currently as capital for regulatory purposes and BUCKLER may pledge the securities to secure its own borrowings. The scheduled maturity dates of the on demand subordinated loan agreements shall automatically be extended by an additional one year, unless the Company notifies BUCKLER of non-renewal, thirteen months in advance, on or before the scheduled maturity dates (see Note 14 to the consolidated financial statements).

Current report

The use of artificial intelligence presents risks and challenges that may adversely impact our business.

Current report

We, our manager, or third-party service providers use, and may continue to use, artificial intelligence (“AI”) in certain business processes, including but not limited to data analysis, investment modeling, risk management, financial reporting, and cybersecurity. While AI technologies have the potential to improve efficiency, accuracy, and decision-making, their use also introduces a number of risks and uncertainties that could adversely affect our business, financial condition, and results of operations.

Current report

AI systems are dependent on the quality and completeness of the data used for training and operation. Inaccurate, incomplete, or biased data can result in flawed outputs, which may lead to suboptimal investment decisions, errors in financial reporting, or ineffective risk management. Additionally, AI models may be subject to “black box” limitations, where the rationale for certain outputs or recommendations is not transparent or easily understood by management or oversight personnel. This lack of transparency can make it difficult to identify, assess, and remediate errors or unintended consequences in a timely manner.

Current report

The use of AI may also expose us to increased cybersecurity risks. AI systems can be targeted by malicious actors seeking to manipulate outputs, exfiltrate sensitive data, or disrupt operations. Furthermore, as regulatory expectations and industry standards regarding the use of AI continue to evolve, we may be required to implement additional controls, documentation, or governance measures to ensure compliance. Failure to do so could result in regulatory scrutiny, penalties, or reputational harm.

Current report

We rely on third-party vendors for certain AI-enabled services and solutions. These vendors may not have adequate controls in place to ensure the reliability, security, or regulatory compliance of their AI systems. Any failure by a third-party provider to manage AI-related risks appropriately could have a material adverse effect on our operations.

Current report

There is no assurance that our use of AI will achieve the intended benefits or that we will be able to effectively manage the associated risks. Any failure to do so could result in financial losses, regulatory action, or damage to our reputation. As AI technologies and their applications continue to develop, the risks and uncertainties associated with their use may increase.

•The fair value of our interest rate swaps represents forecasted future net swap coupon amounts. The fair value of these positions has already been included in total comprehensive income (loss) and total stockholders’ equity. It has been received by us in cash through variation margin payments made by our counterparties, which we recognize as a liability. Both the asset and liability will ultimately go to zero. This exact path of this eventual decline is uncertain and will depend on future changes in interest rates and other factors;

Previous report

After the Fed increased the Federal Funds Rate to a target range of 5.25% to 5.50% in July 2023 to tame rising inflation, it kept the target range at this level until September 2024, stating in 2024 FOMC meetings that the risks to achieving its employment and inflation goals continue to move into better balance. In September 2024, the Fed started reducing its target range, decreasing it by 0.50% to 4.75% to 5.00%, and stating that the risks to achieving its employment and inflation goals were then roughly in balance. The Fed subsequently reduced the target range by 0.25% each in November and December 2024, bringing the target range down to 4.25% to 4.50%.

Previous report

While short-term interest rates fell as the Fed reduced its target range by 100 basis points from September to December, long term interest rates were volatile throughout the year and rose by 69 basis points, negatively impacting the market value of our investments. There were many factors that contributed to the rise in long term rates, including the Fed’s quantitative tightening policies that remained throughout 2024. These policies included reducing the Fed’s holdings of agency mortgage-backed securities and U.S. Treasuries, creating net supply in the market.

Previous report

The fair value of our interest rate swaps represents forecasted future net swap coupon amounts. The fair value of these positions has already been included in total comprehensive income (loss) and total stockholders’ equity. It has been received by us in cash through variation margin payments made by our counterparties, which we recognize as a liability. Both the asset and liability will ultimately go to zero. This exact path of this eventual decline is uncertain and will depend on future changes in interest rates and other factors.

Previous report

At December 31, 2024, the aggregate fair value of our interest rate swaps was $894,714, which compares to the amount of our equity attributable to our common stock of $1,190,240. The fair value of our interest rate swaps represents forecasted present values of future net swap coupon amounts. Variation margin provisions in our swap contracts require our counterparties to post to us cash collateral equal to that fair value. We have used that cash collateral to collateralize or reduce our repurchase financing balances, to acquire additional Agency Securities or to increase our cash liquidity. Future changes in forward interest rates are the primary determining factor in the economic and aggregate financial reporting impact of our swaps on our investment returns, financial position and results of operations.

Previous report

Periodic net swap coupon receipts and payments were forecasted to arrive at the estimated fair values of our swaps. Accordingly, amounts reported as the periodic net coupon effect of our interest rate swaps largely represent values that were previously recognized elsewhere in total comprehensive income (loss). Periodic net swap coupon amounts are largely offset by corresponding adjustments in the fair values of the swaps, which are concurrently reported in total comprehensive income (loss) and total stockholders’ equity, resulting in a relatively minor aggregate impact. When considered with the variation margin requirements, periodic net swap coupon amounts have relatively little practical impact on our current investment, financing or liquidity positions.

Previous report

Terminating interest rate swaps would merely result in the offsetting of our recognized interest rate swap asset and obligation to return cash collateral posted. Termination would have little practical effect on our current investment, financing or liquidity positions. Terminating or entering into new swaps changes our exposure to future interest rate changes.

Previous report

The fair value of our swap positions will ultimately go to zero over their remaining terms, which averaged 76 months as of December 31, 2024. The rate and exact path of this inevitable decline is uncertain and will depend on future changes in expected forward interest rates and other factors. These factors will also drive the future amounts of net swap receipts or payments and corresponding future fair values and variation margin amounts. We also may terminate swaps before their maturity and receive or make final settlement payments based on the estimated fair value of the swap at the time of termination.

Previous report

Significant changes in the number of shares outstanding over time complicate the understanding of periodic per share calculations.

Previous report

GAAP requires that earnings per share amounts be calculated based on the time-weighted average number of shares outstanding during each period. The weighted average shares outstanding used in the denominator of each per share calculation is determined separately for each quarterly and year-to-date period. Therefore, the resulting per share amounts are not additive across periods when the number of shares outstanding is changing significantly. GAAP explicitly recognizes this result (“denominator effect”), even though it is often not material because the number of shares outstanding often remains relatively constant from period to period.

Previous report

We regularly report book value per common share, which is calculated as stockholders’ equity attributable to common stockholders (net of liquidation preferences on preferred stock) divided by the number of shares outstanding. Changes in book value per common share are partially explained by total comprehensive income or loss per share and common per share dividends declared. The residual difference between the beginning and ending book value per share is attributed to the net accretive or dilutive effect of our capital activities (share issuances and repurchases). Consequently, any denominator effect across time periods relating to total comprehensive income or loss per share will result in an equal offsetting effect in the attributed net accretion or dilution.

Previous report

The following tables illustrate these denominator effects for ARMOUR for 2024 and 2023.

Previous report

(1) Per shares amounts are not intended to be added across periods under GAAP. In this illustration, comprehensive loss per common share for the year ended December 31, 2024 and December 31, 2023, is $(0.08) and $0.03 per share, respectively (lower) higher than the algebraic sum of corresponding amounts for the four individual quarters of the year. Similarly, the (dilutive) accretive effect of our capital activity is $(0.08) and $0.03 per common share, respectively (larger) smaller when calculated on an annual basis as compared to the algebraic sum of the individual quarterly calculations.

Previous report

The denominator effect is also present when aggregating days into a month or months into a quarter for purposes of per share calculations. Accordingly, the attributed accretion or dilution we report for a quarter or longer period may not be fully representative of the daily results of our capital activities.

Previous report

ACM has voluntarily waived a portion of its contractual management fee. ACM has reduced, and may further reduce, the amount of or discontinue entirely its voluntary fee waiver without our consent.

Previous report

During the years ended December 31, 2024, December 31, 2023 and December 31, 2022 ACM voluntarily waived management fees of $6,600, $6,600 and $7,800 respectively. ACM is currently waiving $550 per month of its contractual management fee until ACM provides further notice to ARMOUR (see Note 9 to the consolidated financial statements). ACM may prospectively further reduce the amount of or discontinue entirely its voluntary fee waiver at its sole discretion and without requiring our consent.

Previous report

The following table illustrates the relationship between Distributable Earnings and net interest income and total comprehensive income (loss) for the year ended December 31, 2024 and December 31, 2023.

Previous report

Distributable Earnings is based on the historical cost basis of our Agency Securities and interest rate swaps, while we report substantially all of our assets and liabilities at current fair values. As a result, Distributable Earnings may include amounts that were recognized and reported elsewhere in our consolidated financial statements previously. For example, the net coupon effect of interest rate swaps is the primary driver of market value adjustments on these positions that were recognized in total comprehensive income (loss) and total stockholders’ equity in prior periods.

Previous report

We have returned, and may continue to return, capital to stockholders by paying dividends in excess of our comprehensive income and/or repurchasing shares, which may adversely affect our business.

Previous report

Our Board of Directors considers Distributable Earnings when determining the level of dividends on our common stock. Distributable Earnings tends to be more stable over time and this practice is designed to increase the stability of our common stock dividend from month to month. However, Distributable Earnings excludes gains and losses in portfolio value that are reflected in total comprehensive income (loss) computed in accordance with GAAP. These differences cause us to distribute common stock dividends that differ from our total economic return. Since 2010, ARMOUR has distributed common stock dividends totaling approximately $2,144,101 while incurring cumulative total comprehensive (loss) attributable to common stockholders of $(1,078,961). Such losses include approximately $(622,300) in 2013 and $(539,942) in the first quarter of 2020 and $(399,914) in the first three quarters of 2022.

Previous report

Dividends paid in excess of comprehensive income and common and preferred stock share repurchases will reduce our capital base and our ability to invest in MBS without increasing financial leverage. Reducing our capital base will increase our expense ratio and could potentially reduce the availability of our repurchase financing and interest rate swap hedges. We will be more likely to consider future returns of capital to stockholders when the market trading price for our common stock represents a significant discount to our book value.

Previous wording

We invest predominately in MBS backed by loans with fixed interest rates, and to a lesser extent from time to time, in MBS backed by loans with interest rates that adjust on a regular basis, usually either monthly or annually. Our MBS have maturities ranging from 10 to 30 years (although average lives are much shorter due to amortization and prepayments). Our repurchase agreement borrowings generally have maturities ranging from one to 90 days. This mismatch in the interest rate terms between our assets and our liabilities is the primary source of our ability to generate positive net interest income because long-term interest rates tend to be higher than short-term rates. Short-term and long-term interest rates do not always move together. If short-term rates increase faster than long-term rates, the difference between the two may become zero or negative, and we may not have the ability to generate positive net interest income.

It can be difficult to predict the impact on interest rates of unexpected and uncertain global political and economic events, such as pandemics, epidemic disease, warfare (including the ongoing war between Russia and Ukraine and Middle East hostilities), economic and international trade conflicts or sanctions, the change in the political makeup of the U.S. Congress, or changes in the credit rating of the U.S. government, the United Kingdom, or one or more Eurozone nations; however, increased uncertainty or changes in the economic outlook for, or rating of, the creditworthiness of the U.S. government, the United Kingdom, or Eurozone nations may have adverse impacts on, among other things, the U.S. economy, financial markets, the cost of borrowing, the financial strength of counterparties we transact business with, and the value of assets we hold. Any such adverse impacts could negatively impact the availability to us of short-term debt financing, our cost of short-term debt financing, our business, and our financial results.

Previous wording

Changes in Fed policy affect our financial results because our cost of funds is largely dependent on short-term rates. An increase in our cost of funds without a corresponding increase in interest income earned on our investments in securities causes our net income to decline. We cannot predict the impact of any future actions by the Fed on the prices and liquidity of the securities in which we invest. Future Fed action could reduce the value of our assets, reduce the spread on our investments and/or decrease our book value. Changes by the Fed in its securities purchase programs or other monetary policy could materially adversely affect our business, financial condition and results of operations and our ability to pay distributions to our stockholders.

Previous wording

Agency Securities backed by single-family residential loans allow the underlying borrowers to prepay their loans without premium or penalty. When borrowers default on their loans, the GSE or government entity that issued or guaranteed the Agency Securities (including Agency Securities backed by multi-family loans) pay off the remaining loan balance. Those prepayments, including default payoffs, are passed through to us, reducing the balance of the Agency Security. We generally purchase Agency Securities at premium prices, and the premium amortization associated with prepayments reduces our interest income.

We endeavor to achieve net proceeds representing a higher percentage. For 2024, we realized net proceeds that averaged approximately 98.7% of recently estimated book value, resulting in an aggregate dollar dilution of $3,487. We also consider the favorable impact to existing stockholders of spreading administrative and operating expenses over an increased number of common shares.

Previous wording

The management agreement entitles ACM to receive a management fee payable monthly in arrears calculated based on gross equity raised (see Note 9 and Note 15 to the consolidated financial statements). The annualized management fee rate is (a) 1.5% of gross equity raised up to $1.0 billion plus (b) 0.75% of gross equity raised in excess of $1.0 billion. Gross equity raised includes the total amounts of paid in capital relating to both our common and preferred stock, before deduction of brokerage commissions and other costs of capital raising. Amounts paid to stockholders to repurchase common and preferred stock, before deduction of brokerage commissions and costs, reduce gross equity raised. Dividends specifically designated by the Board as liquidation dividends reduce the amount of gross equity raised. To date the Board has made no such specific designation of any of the dividends paid by the Company. Pursuant to prior versions of the management agreement, gross equity raised was reduced by $123,199 to reflect dividends paid in in excess of taxable income prior to January 1, 2016. Regular dividends (including those treated as a return of capital for tax purposes on or after January 1, 2016) and investment losses do not reduce gross equity raised. Investment gains and net income do not increase gross equity raised. Accordingly, we have experienced and may continue to experience reductions in our total stockholders’ equity without a commensurate reduction in management fee expense.

Dividends specifically designated by the Board as liquidation dividends reduce the amount of gross equity raised. To date the Board has made no such specific designation of any of the dividends paid by the Company. Regular dividends (including those treated as a return of capital for tax purposes on or after January 1, 2016) and investment losses do not reduce gross equity raised. Investment gains and net income do not increase gross equity raised. Accordingly, we have experienced and may continue to experience reductions in our total stockholders’ equity without a commensurate reduction in management fee expense.

Previous wording

At December 31, 2024 gross equity raised totaled $4,498,880 resulting in an effective contractual management fee rate of 0.92% prior to management fees waived and 0.77% after management fees waived, of that base. The resulting annualized contractual management fee of $41,242 represents 3.03% of the Company’s total stockholders’ equity determined in accordance with GAAP of $1,361,415 at December 31, 2024.

Current wording

At December 31, 2025 gross equity raised totaled $5,366,343 resulting in an effective contractual management fee rate of 0.89% prior to management fees waived and 0.77% after management fees waived, of that base. The resulting annualized contractual management fee of $47,747 represents 2.11% of the Company’s total stockholders’ equity determined in accordance with GAAP of $2,261,053 at December 31, 2025.

Previous wording

We may not terminate our management agreement with ACM before December 31, 2029, except for cause or in connection with the liquidation of ARMOUR or certain business combination transactions. For the period from January 1, 2025 through December 31, 2029, ARMOUR is obliged to pay contractual management fees totaling approximately $206,210 based on gross equity raised as of December 31, 2024, the date of the most recent management contract extension.

Current wording

We may not terminate our management agreement with ACM before December 31, 2029, except for cause or in connection with the liquidation of ARMOUR or certain business combination transactions. For the period from January 1, 2025 through December 31, 2029, ARMOUR is obliged to pay contractual management fees totaling approximately $190,992 based on gross equity raised as of December 31, 2025, the date of the most recent management contract extension.

Previous wording

The term “cause” is limited to those circumstances described in the management agreement with ACM and generally includes a final court determination of material breach of the management agreement, willful misconduct, gross negligence or fraud. Upon a termination by us in connection with the liquidation of ARMOUR or certain business combination transactions the management agreement provides that ARMOUR will pay ACM a termination payment equal to four times the contractual base management fee payable to ACM in the preceding full 12 months, calculated as of the effective date of the termination of the agreement. ACM's voluntary fee waiver does not reduce the amount of such termination payment. The contractual management fee payable to ACM for the 12 months ended December 31, 2024, was $39,726. The contractually required termination payment would increase the effective cost to us to terminate the management agreement in connection with the liquidation of ARMOUR or certain business combinations and adversely affect ARMOUR's attractiveness as a potential business combination target.

Current wording

We consider Distributable Earnings as a measure of our investment performance and discuss our periodic financial results in terms of Distributable Earnings in our press releases and conference calls with equity analysts. We believe that Distributable Earnings is useful to investors because it is related to the amount of dividends we may distribute. Distributable Earnings is a non-GAAP measure defined as net interest income plus TBA Drop Income adjusted for the net coupon effect of interest rate swaps minus net operating expenses. Distributable Earnings differs, potentially significantly, from net interest income and from total comprehensive income (loss) (which includes realized gains and losses and market value adjustments).

Previous wording

Because Distributable Earnings excludes gains and losses in portfolio value, using it as a measure of investment performance may encourage ACM to make portfolio decisions on our behalf that have the effect of accelerating the realization of losses and delaying the realization of gains. For example, in declining interest rate environments, we may replace interest rate swaps that have declined in value with new swaps requiring a lower fixed coupon payment while retaining in portfolio appreciated mortgage securities. Conversely, in rising interest rate environments, we may replace mortgage securities that have declined in value with new, higher coupon securities while retaining interest rate swaps that have increased in value.

At December 31, 2024, BUCKLER provided approximately $4,895,003, or 45.7% of ARMOUR’s repurchase financing. BUCKLER is subject to various broker-dealer regulations. BUCKLER’s failure to comply with these regulations and facilitate attractive repurchase financing and its ability to conduct business with third parties could adversely affect ARMOUR’s funding costs, “haircuts” and/or counterparty exposure. We cannot guarantee that BUCKLER will be able to provide repurchase financing on more attractive terms in the future.

Current wording

We hold a 10.8% equity ownership interest in BUCKLER and additionally, provided BUCKLER with $250 million in additional regulatory capital.

Previous wording

The primary purpose of our investment in BUCKLER is to facilitate our access to repurchase financing, on potentially more attractive terms (considering rate, term, size, haircut, relationship, and funding commitment) compared to other suitable repurchase financing counterparties. To facilitate this, ARMOUR holds a 10.8% equity ownership interest in BUCKLER and has committed to provide on demand a subordinated loan to BUCKLER in an amount up to $200 million. The commitment extends through March 20, 2026, and is collateralized by Agency and/or U.S. Treasury Securities owned by ARMOUR and pledged to BUCKLER. The commitment is treated by BUCKLER currently as capital for regulatory purposes and BUCKLER may pledge the securities to secure its own borrowings (see Note 15 to the consolidated financial statements).

Previous wording

ARMOUR continues to maintain active repurchase financing arrangements with numerous other counterparties with the intention of reducing our risk of relying primarily on BUCKLER. At December 31, 2024, we had repurchase borrowings from 17 different counterparties including BUCKLER. However, there can be no assurance as to the availability, terms, or cost of additional repurchase financing that might be available from other counterparties if we needed to replace BUCKLER’s financing capacity, particularly on short notice or during times of market distress.

BUCKLER has acted as placement agent for 83% of the shares of common stock that ARMOUR has issued through its ATM programs in 2024. BUCKLER’s commission rate for these placements has been lower than the commission rates of other placement agents involved in our ATM program. Placement commissions represent a significant contribution to BUCKLER profitability. If BUCKLER became unable to participate in our ATM program, our placement costs would increase. If we reduce the volume of ATM placements with BUCKLER, its profitability may be adversely affected.

Previous wording

So long as we are providing BUCKLER with additional regulatory capital, our independent directors must approve, in their sole discretion, any third-party business engaged by BUCKLER. However, we cannot guarantee that BUCKLER’s pursuit of business with third parties will not incur losses for us or that BUCKLER will be able to continue to provide us with attractive repurchase financing.

Current wording

The Company cannot direct BUCKLER's daily activities. However, the BUCKLER operating agreement contains certain provisions to benefit and protect the Company. One of those provisions requires approval from the independent directors of the Company of any third-party business engaged by BUCKLER so long as any loan amount of indebtedness remains outstanding under the on demand subordinated loan agreements. We cannot guarantee that BUCKLER’s pursuit of business with third parties will not incur losses for us or that BUCKLER will be able to continue to provide us with attractive repurchase financing.

Previous wording

We are subject to conflicts of interest arising out of our relationship with ACM and its affiliates, including BUCKLER. An entity affiliated with Mr. Ulm is one of the two general partners of ACM, and each of Mr. Ulm, Mr. Staton and Mr. Bell is a limited partner in ACM. ACM controls BUCKLER.

For U.S. federal income tax purposes, we previously have incurred net capital losses. Such net capital losses may be carried forward for five taxable years and generally used to offset undistributed taxable net capital gains realized during the carry forward period. Net capital losses realized totaling $(15,606), $(732,477), $(472,002), and $(46,823) will be available to offset future capital gains realized in 2026, 2027, 2028 and 2029 respectively. Any capital loss carry forward that we have not used to offset undistributed otherwise taxable net capital gains will expire after the end of such five-year period, and will no longer be available to us. Capital loss carry forwards totaling $(1,071,379) expired unused in 2024 and prior years because we did not generate enough taxable net capital gains during that period relative to our level of distributions. Our current practice of declaring dividends based on non-GAAP Distributable Earnings increases the likelihood that net capital gains realized will be treated as distributed in the year realized. In the absence of offsetting net capital loss carry forward amounts, we will be required to make timely distributions of future net capital gains realized, or alternatively, pay U.S. federal income tax on such realized net capital gains not distributed.

We conduct our business so as not to become regulated as an investment company under the 1940 Act. If we were to fall within the definition of investment company, we would be unable to conduct our business as described in this Annual Report on Form 10-K. Section 3(a)(1)(A) of the 1940 Act defines an investment company as any issuer that is or holds itself out as being engaged primarily in the business of investing, reinvesting or trading in securities. Section 3(a)(1)(C) of the 1940 Act also defines an investment company as any issuer that is engaged or proposes to engage in the business of investing, reinvesting, owning, holding or trading in securities and owns or proposes to acquire investment securities having a value exceeding 40% of the value of the issuer’s total assets (exclusive of U.S. Government securities and cash items) on an unconsolidated basis. Excluded from the term “investment securities,” among other things, in Section 3(a)(1)(C) of the 1940 Act, as defined above, are U.S. Government securities and securities issued by majority-owned subsidiaries that are not themselves investment companies and are not relying on the exclusion from the definition of investment company set forth in Section 3(c)(1) or Section 3(c)(7) of the 1940 Act.

In the future, we may raise capital through the issuance of debt, preferred equity or common equity securities. Upon liquidation, holders of our debt securities and preferred stock, if any, and lenders with respect to other borrowings will be entitled to our available assets prior to the holders of our common stock. Additional equity offerings may dilute the holdings of our existing stockholders or reduce the market price of our common stock, or both. Additional series of preferred stock, if issued, could have a preference on liquidation distributions or a preference on dividend payments that could limit our ability to pay dividends to the holders of our common stock. Sales of substantial amounts of our common stock (including shares of our common stock issued pursuant to our 2009 Stock Incentive Plan, as amended), or the perception that these sales could occur, could have a material adverse effect on the price of our common stock. Because our decision to issue debt or equity securities in any future offering will depend on market conditions and other factors beyond our control, we cannot predict or estimate the amount, timing, or nature of our future offerings. Thus, holders of our common stock bear the risk of our future offerings reducing the market price of our common stock and diluting the value of their stock holdings in us.
